DECALCOMANIA-TRANSFERRING MACHINE.

Specification of Letters Patent. v Patented Feb, 24, 192th,

Application filed August 10, 1918. Serial No. 249,315.

New York, have invented a certain new and useful Im rovement in Decalcomania-Transferring M achines, of which the following is a specification.

The present invention relates to an improvement in decalcomania transferring machines.

It has been proposed heretofore to construct a decalcomania transferring machine employing 5. conveyer or endless belt upon which the article or articles to be stamped all occupy thesame plane and are presented in that plane in succession to the action of the heatedpresser iron and the transfer .tape upon which the decalco-manias are tem-' porarily impressed, in order to effect a transfer of the decalcomanias from the tape to the articles. In such machines, the transfer tape usually occupies a definite plane and the presser iron has a certain, definite range of action. Such machines are, accordingly, not adapted for operation on articles which are arranged or stacked one upon another in piles. And it has not been heretofore proposed, so far as is known, to

construct a decalcomania transferring machine adapted for operation on articles arranged in stacks or piles, where the contiunity of the pile is not permitted to be broken.- The machine of the present invention is particularly adapted for transferring decalcomanias to articles arranged in piles, although it may be equally successively employed on articles all occupying the same plane.

Where the articles are arranged in piles, as each article is stamped or receives a decalcomania, it is folded back in order to expose the neXt underlying article to the action of the transfer tape and the heated presser iron. Upon the completion of the transferring operation upon the pile of articles, they are folded loack to their original position. and so the continuity of the pile is not disturbed. The pile of articles to be stamped rests upon a work support and as each article is stamped and folded back to expose the next underlying article, the presser iron descends progressively lower toward the work support.- It is thus seen that each article is acted upon in a different plane of operation. A proper transference of the decalcomania from the transfer tape to the article requires not only that the presser iron be at a certain temperature, but

also that it be in engagement with the trans- 1 fer tape and the article for a predetermined and requisite length of time under the requisite amount of pressure. The application of the proper amount of heat for the required time under a certain amount of pressure effects a proper transference of the decalcomania. If the heated presser iron is in engagement withthe transfer tape and the article for either too long a time or not long enough, a successful transference of the decalcomania is not effected; in the first instance, because the composition of the decaloomania is crystallized and, in the second instance, because the (lecalcomania is not properly loosened from. the transfer tape.

One feature of the present invention is to provide a decalcomania transferring machine with mechanism of such construction that the presser iron will be in operation, that is to say, in engagement with the transfer tape, pressing 1t' against the article to be stamped, for a predetermined length of time, regardless of the position the article occupies in the pile. In other words, Whatever the distance from the table the presser iron occupies in performing its transferring operation, it remains in each operative position an equal and predetermined length of time. his mechanism also assures that the presser iron will exert an equal pressing force upon each article, irrespective of its position in the pile. As a result of this action of the presser iron, the operation of removing the decalcomanias from the transfer tape and'causing them to adhere to the articles isefi'ectively performed.

Inasmuch as the presser iron traverses varying distances in order to press the transfer tape against the articles to be stamped, it will'be recognized that the transfer tape must normally be at such distance from the work support as not-to interfere with a fresh supply of articles placed on the work support, and yet must be so supported asv to be movable into close proximity with the work support. Atnother feature of the invention various positions of operation. The transfer tape is supported in such manner that it passes in close proximity to the heated presser iron, If, as above pointed out, the decalcomanias remain too long in the presence of heat, they become crystallized; ac-

cordingly, it is another feature of the mvention to feed the transfer tape so that the portions thereof upon which the decalcomanias are impressed come into position to be acted upon only as the presser iron moves into its operative position. Other features of the invention will a pear as the description of the machine em odying the invention proceeds. The invention consists in the improved decalcomania transferring machine hereinafter described and particularly pointed out in the appended claims.

The pile or stack of goods, commonly fabrics or articles of apparel, to which the decalcomanias are to be applied rest upon a work support or work supporting table 87, in position to be subjected to the action of a heated presser iron 64, which acts to heat and press a decalcomania-carrying web or tape 56, known as the transfer tape, against the artlcles for a predetermined length of I time under a predetermined amount of pressure. The presser 64 is supported in a presser carrying head projecting forwardly from a slide 39 mounted for reciprocating movements in vertical guide-ways 40 formed in the upper part 3 of the frame I of the machine. The presser is heatedin.

the usual way by electricity conducted through a wire 86. The presser 64 is provided with a shank 75, which is received in an openin in the upper part 72 of the head 65. Che'c -nuts screwed on to the presser shank limit the downward movement of the presser relatively to the head 65. A spring 74 surrounding the shank of the presser tends to force it downwardly against the transfer tape 56. The presser is lifted against the action of the spring 74, in order to normally hold the presser away from the tape'bymeans of a lever 76 pivoted at 77 in ears 78 carried by the head 65. The forward end of the lever'7 6 is received in a recess fashioned in the shank of the presser,

and the rear end of the lever is bifurcated,

as shown in Fig. 9, so as to accommodate pivoted to the lever at 80. Springs 82, connected at their rear ends to pins carried by the lever 76 and at their forward ends to a pin 81, carried by the pawl, tend to press the hpper hook-shaped end of the pawl forward into engagement with a lug 73 formed on the upper part 72 of the head 65. The lever 76 is actuated to raise the presser 64 against the action of the spring 74, when by the upward movement of the slide 39 the upper edges 83 of the rear end of the lever 76 and the horizontal arm of the pawl 79 are brought into engagement with the lower endof astop pin 84, adjustably secured in a bracket 85 fastened to the upper part 3 of the frame of the machine, as shown inFig. 2.' This is the normal or inoperative position of the presser and its associated parts, the presser 64 and its head 65 always rising to this position after having been forced down against the articles in order to impress a decalcomania thereon.

As the head 65 descends toward the work I support 87 the lever 76 and pawl 79 become disengaged from the stop pin 84; thereupon the sprin 74 is free to force the presser 64 downwardly below the bottom of the presser carrying head and against the transfer tape 56, as shown in Fig. 3; and the springs 82 are free to move the hookshaped'end of the pawl 79 into engagement with the lug 73, so asto lock the presser 64 inv its lowered position in fixed relation with the head 65. This enables the presser to be forced firmly against the articles during the transferring operation.

The slide 39 is moved downwardly to bring the presser 64 into operative engagement with the transfer tape 56 and the pile of articles on the work support by means of a rod 25 connected at its upper end with the slide and at its lower endwith an eccentric 24, loosely mounted on a shaft 13 jonrnaled in bearings 14 and 15 rising from a bracket 10 fixed on the lower part 2 of the frame of the machine. A- turnbuckle 38 affords r0- vision for adjusting the rise'and fall- 0 the menace slide and the presser carr ing head. The cam 24 carries a segmental gear 23, which is arranged to be engaged and driven by a pinion 18 having a conical central opening therein adapted to'engage a truncated cone 17 formed on the outer end of an arm 16 fastened to the shaft 13. The pinion 18 is I held in position on the cone 17 by means of a pin 20, the large end 19 of which is received in an annular recess of the pinion. A. recess is formed in the outer end of the arm 16 to accommodate a spring 22, the outer end of which presses against a nut 21 received on the end of thepin 20. By turn ing the nut 21 the tension of the spring--22 may be regulated so as to cause the inion 18 to turn upon the cone 17 with di culty.

When the machine is started in operation, a counter-clockwise movement is imparted to the shaft 13 and arm 16 so as to bring the pinion 18 into engagement. with the adjacent end of the segment 23. The friction of the Pinion 18 upon the cone 17 is such that the pinion by its'engagement with the seg ment 23 turns the cam 24, so as to impart a downward movement to the r06. 25, thereby moving the head 65 and the presser toward the work support 87. When the presser comes into engagement with the pile of ar ticles on the work support and it is arrested thereby, the pinion 18 is then caused by the constant turning movement exerted upon the arm 16 by the shaft 13 to turnon the cone 17 and so travel over the teeth or" the segment 23 until it reaches the other end thereof; whereupon, the segment being released from the pinion, the head 65 is returned to its raised or inoperative position. The length of time required for the proper softening of the sizing by which the decalcomania is held on the tape so that the de calcomania may become loosened from the tape and be impressed upon the article is determined by the length of the segment 23. Where a shorter time is required, the segment will be correspondingly shortened; and where a longer interval of time is necessary, the segment will be correspondingly lengthened. It. is obvious the same results can be obtained by regulating the speed of the shaft 13. The force with which the presser is pressed against the articles is determined by the tension which the spring 22 exerts in holdin the pinion 18 against the cone 17. It wil thus be recogmzed'from' the 'above description that whatever the I operative position of the presser, whether relatively near to or far from the work support, the presser will act to press the transfer tape against each article for an equal and* predetermined length of time under a constant and predetermined pressure, and

so effect, when, properly heated, a successful transference of the decalcomanias-from the tape to the articles.

The slide 39 is moved upwardly to return the presser into its normal or inoperative position by means of the spring 45, surrounding a rod 42, the upper end of which is adjustably secured to a bracket t1 integral with the slide 39. x The upper end of the spring 15 engages a disk 1% fastened upon the rod 4:2,and the lower end of the spring engages the corresponding disk 1-6 which rests upon. the upper end of aguide 47, in which the lower end of the rod 12 slides. The upper end of the rod slides in a guide 48. The tension of the spring 45 may be regulated by adjusting the nuts 43. In order that the head and the parts carried by it may be returned to their raised position without shock or jar to the ma- 'turned to such position as to register and lock with a bushing 28 carried by a worm? gear 12 loosely mounted upon the shaft 13. The locking pin 27 is held from end-wisp movement by means of a set-screw 29. The outer end of the locking pin 27 is provided with a finger 30 which is yieldingly pressed toward the shaft 13 by a spring 31. The lower or free end of the finger 30 is normally in engagement with a shoulder 32 formed on a dog 33 pivoted at 34: in the frame of the machine. When the finger 30 is in engagement with the shoulder 32 of the dog 33, the Pin 27 is out of lockin engagement with the bushing 26 so that t e worm gear 12 cannot drive the clutch 28. The free outer endof the dog 33 is connected with a treadle 36 by a link 35. A. spring 37 surrounding the link tends to raise the treadle 36 and the dog 33 so as to hold the shoulder 32 on the dogiin the path of movement of the finger 30. A stop pin 38 limits the upward movement of the dog.

The worm gear 12 is constantly driven by a worm 11, fixed upon the main shaft 8 of the machine, which is journaled in a long bearing 9 supported on the bracket 10. The shaft 8 is provided with a clutch member 7 driven by a cofiperating clutch member 6 secured on the outer end of the shaft 5 of the motor 4, which constitutes the source of power of the machine. vThe machine is started in operation by the workman forcing the treadle down so as to disengage the dog .33 from the finger-130. Thereupon the spring 31 acts to turn the'locking pin 27 so as to lock the clutch 28 against the worm ear 12.

'ried by a reel 57 fulcrumed on a stud 58,

adapted to accommodate a stack orvpile of articles of considerable thickness, which diminishes as thesucceeding top layers of the articles are operated upon, so that when the last article resting on the work support is reached, the presser must descend into close proximity with the table; it is necessary, therefore, that the transfer tape be nor mally held in such position as to permit the stack or pile of articles to be interposed between it and the work support, and it is also necessary-that the transfer tape be so supported that it may be moved into engage-- ment with each article, regardless of its position in the pile. After a decalcomania s transferred from the transfer tape to an article, it is necessary to present a fresh de-- calcomania to the action of the presser. The means for supporting the transfer tape and the means for feeding it will be conjointly described. The roll of transfer tape is carfixed in brackets 59 extending rearwardly from the machine.- From the reel 57 the transfer tape asses under a roll 53 over a roll 54 and un er another roll 55. The rolls 53 and 54 are journaled in the outer end of the bracket 49, and the roll 55 is supported in bearing blocks which slide loosely in slots formed in the upper part of the outer end of the bracket 49 so that the roll 55 may press against the transfer tape under the action of gravity. From the rolls 54 and 55 -the tape passes through an aperture 62,

formed in the slide 39, and under a leaf spring 63 secured to the bottom of the presser carrying head 65, and thence over the-lower open side of the head .65. up through a slot formed by a guide-way 66, secured to the front of the head and thence over arail 67 to the feed rolls 68 and 69. From the feed rolls the tape passes through a chute 61, supported by the upper part of the machine and by the upper part of the bracket 59. The above described construction is such that the. part of the transfer tape to be acted upon by the presser is carried toward ard from the table with the head and, accordingly, the tape never interferes with placing work in the machine,

.having regard to the capacity of the lilaarticles,

chine, whatever the thickness of the pile of Inasmuch as a portion of the transfer tape 56 is carried in close proximity to the under surface of the heated presser iron 64, crystallization of the sizing by which the decalcomania is held on the-transfer tape and Icry'stallization of the other constituents of the decalcomania is prevented by feeding the transfer tape forward whent e presser is descending into operative position, so that the length of time the presser is in engagement with the transfer tape will be just sufficient to melt the sizing, and also the adhesive which serves to fasten the decalcomania upon the article receiving it. The successive lengths of transfer tape carrying the decalcomanias are successively brought under the presser 64 as the presser descendsinto operative position by holding the feed I roll 68 stationary during the first part of ,wardly from the feed rolls 68 and 69.

The lower feed roll 68 is provided with a bushing 94 (Fig. 8), which is loosely mounted on a shaft 95, journaled in the upper end 96 ofthe frame of the machine. One end of the roll is recessed to accommodate a spring clutch 99 loosely but snugly engaging the shaft 95, the outer end of the spring 99 being received in a hole in the roll. This construction is such that when the shaft 95 is driven in one direction, it tends to unwind the spring and, therefore, no turning movement is imparted to the roll 68; but when the shaft is turned in the opposite direction, it tends to wind up the spring, (which fits so closely over the shaft 95 that there is practically no lost motion) and so the turning of the shaft 95 imparts a turning movement to the roll 68. The opposite end of the roll 68 is recessed to receive the hub of a ratchet wheel 98, which is fixed to the roll 68, but is loosely supported on the shaft 95. Alongside the ratchet wheel 98 a cam 97 is rigidly secured to the shaft 95. The cam 97 is adapted to be brought into-engagement with the curved part of a pawl 103 pivoted at 102 on the frame of the machine. The pawl 103 is provided with a shoulder 104 arranged to be engaged by the teeth of the ratchet wheel 98. A spring 106, one end of which is fastened to the free end of pawl 103 and the other end of which is fastened to a'pin 107, tends to move the shoulder 104 into the path of movement of the teeth of the ratchet wheel. These parts are constructed and arranged in such manner that during the first part of the downward movement of the presser carrying head 65, the shoulder 104 is engaged by one of the teeth .of the ratchet wheel, thereby preventing the turnin movement of the feed roll 68; but when t e requisite length of tape has been drawn from the supply roll, so as to position afresh decalcomania under the presser '64,"then the cam 97 is brought into engage-,

ment with the awl 103 to release the shoul der 104from t e ratchet wheel 98, so as to -permit the feed roll 68 to turn backwardly,

thereby permitting the used tape to be inclosed in a guard 109. During the first part of the downward movement of the head 65, while the appropriate length of tape is being drawn from the source of supply, and while the shoulder 104 is in engagement with the ratchet wheel 98, the turning movement of the pinion 101 and the shaft 95 impartedby the descending rack is not communicated to the feed roll 68, because theturning of the shaft 95 in this direction tends to unwind the spring clutch 99. When the shoulder 104 ,of the pawl 103 is disengaged from the ratchet wheel 98, the roll 68 is turned in a reverse or backward direction (to permit a backward movement of the ta-pe), not through'its shaft 95, but by the pulling action exerted upon it by the descending head 65; and in this connection it will be noted that ,the roll 68 is provided at its outer ends with pins 70 for engagement with perforations along the edges of the transfer tape. When the head 65 rises, the movementamparted to thepinion 101 and I the shaft 95 by the rack 108 is imparted to the roll 68 by the spring clutch 99. While the head is rising, the turning movement 1 thereby imparted to the roll 68 serves to take up the slack in the tape caused by the rising of the head.

It is to be observed that the length of transfer tape advanced during each cycle of operation into position under the presser 64 bears a definite relation to the even divisions of the circumference of the feed roll 68. The number of teeth on the ratchet wheel 98 equals the number of feed lengths of transfer tape necessary to equal the circumference of the feed roll. @n each feed length of tape one decalcomania is impressed. By means of this construction a definite and positive amount of tape is advanced during each feed ng operation. The cam 97 is sopositicned with respect to the teeth on the ratchet wheel that it does not come into envagement with the pawl 103 "to release the houlder 104 from the r tchet wheel until the requisite amount of transfer tape has been drawn from the source of supply. The ratchet wheel being held fast while the head 65 is descending a sutlicient distance to draw the requisite amount of tape from the source of supply, and then released to turn backward with the feed roll 68 when the head 65 rises again and a forward movement is imparted to the feed roll and the ratchet 69 lightly against the transfer tape.

wheel, the next succeeding tooth of the ratchet wheel will be presented to the shoulinstance, the ratchet wheel 98 has three teeth, and so th'ree lengths of transfer tape are necessary to equal the circumference of the feed roll 68. Each section of the tape carrying a decalcomania is called a length of tape.

The upper feed roll 69 is securedto a shaft 88 journaled in the bifurcated forward end of a frame 90 pivoted in ears 92 rising from the upper part of the frame of the machine. Spring-pressed plungers 921 (Fig. 4) engaging with the frame 90 serve to press thesroll to pins 93 adjustably secured in the frame 9% determine the amount of downward movement of the roll 69. Grooves 71 formed in the roll 69 accommodate the drive pins of the roll 68.

The various steps in the operation of the improved decalcomania transferring machine will be briefly recapitulated. With the parts in their normal position, as shown in Figs. 1 and 2, and the presser'carrying head 65 and its associated parts in raised position, so as to permit the stack or pile of articles to be stampedto be placed ,on the work support, the workman places the work in proper posit on on the support and presses the treadle 36. This act dise'ngages the dog 33 from the finger 30, permitting the spring 31 to turn the locking pin into such position that it will register with and be received in the bushing 26 so as to lock the clutch 28 to the constantly driven worm gear 12. Thereupon the rotation of the shaft 13 will carry the crank arm 16 and its pinion 18 into engagement with the segmental gear 23. The friction ofthe pinion 18 upon the cone 1? is such as to permit the pinion to turn the seg: ment 23 and the parts connected with it. The turning of the eccentric 24 results in the downward movement of the slide 39 and the presser carrying head 65. As the head 66 descends, the lever 7 6 and pawl 7 9 are released from the stop pin 84, so as tc permit the spring 74 to force the heated presser iron 64 below the bottom of the head 65 and into engagement with the transfer tape 56. The spring 82 is also released to force the latch 79 into engagement with the lug 73 so as to lock the presser in fixed relation with the a lot? Vl hen by the descent of the presser carrying head the requisite amount of transfer tape has been drawn from .the reel 57 so as to I that as the head 65 continues to descend toward the work support, it may pull the used tapejwith it and not disturb the position of the decalcomania in engagement with the presser. scend, the presser iron forces the tape against the topmost article of the pile on the work support. When the resistance becomes sufficiently great to overbalance the friction of the pinion 18 upon the cone 17, the pinion turns and rides over the teeth of the segment 23. The length of time required for the passage of the pinion over the segment- 23 determines the length of time the presser shall be in engagement with the tape and the pile of work. This length of time is suflicient to effect a proper transference of the decalcomania from the tape to the article. When the pinion 18 disengages itself from the segment 23 the spring 45 acts to raise ,the slide'39 and the parts connected with it,

thereby restoring the parts to their normal posltion. The dash pot 52 causes the slide and its connected parts to rise into their normal or inoperative position without shock. As the head 65 rises, the rack 108 turns the feed roll 68 in a forward direction to take up the slack in the transfer tape. The Workman now removes or folds back the article stamped and again presses on the treadle 36 so as to cause the presser to again come intooperative position. If desired, the treadle may be permanently held down and then the parts will automatically perform their cycle of operation, the workman removing or folding back each article as it is stamped. As the successive articles are stamped and removed or folded back, so that v the presser descends progressively lower toward the work sup-port to perform the next succeeding operation, the friction of the pinion 18 on the cone 17 and the length of the segment 23 assure that the presser will exert an equal force upon each article and will be in contact with each article an equal and predetermined length of time.

The machine has been described as being particularly adapted for operation upon a stack or pile of articles, the thickness of which progressively diminishes as the succeeding articles are stamped. It will be recognlzed, however, that the machine of the invention is not to be limited in its application to operation on stacks or piles of articles, inasmuch as it may equally well be employed upon a succession of articles all occupying the same plane, requiring the As the head continues to de is claimed is 1.
